Please, don't publicize lame strategies and exploit abuses.
The game is currently too boring to add up more people building phantom wire or bugging buildings blocking the doors.
Anyone winning games doing that should feel ashamed of himself.
Anyone defending himself against spawning squads behind his line should feel ashamed of himself.
Having to spend 30 or more muni to mine every door on the map is better, hm no.
I wouldn't say it's unfair, in the end it's just one squad behind your lines, not a whole army.
Burning down (wiring/mine/democharge/ whatever) the few neuralgic buildings takes a passable effort.
I hope that's sarcastic, all these buildings on anger, lol.
